Which company owns MAC address prefix C8:AC:35?

MAC address prefix C8:AC:35 is registered to PiLink Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C8:AC:35 has a network interface built by PiLink Co., Ltd..

What is the OUI C8:AC:35?

C8:AC:35 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PiLink Co., Ltd.. It covers every address from C8:AC:35:00:00:00 to C8:AC:35:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-AC-35.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C8:AC:35:00:00:00 that is C8:AC:35 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is PiLink Co., Ltd. located?

PiLink Co., Ltd. is listed at VORT Shin-Yokohama 9F. 3-2-6 Shin-Yokohama Kohoku-ku, Yokohama-shi Kanagawa JP 222-0033 in the IEEE OUI registry entry for C8:AC:35. This is the address the organization registered with the IEEE, which may differ from its current operating address.
